As you know ....its not our "stature" .....its about the dimension from the shoulder to the cheek bone.../ some guys have "no necks"....and we're all somewhere in between.
"Fit" for me changes a little ...if I gain a lot of weight / or lose a lot of weight ( yeah, that's funny ..) ....but I tend to accumulate some weight in my cheeks...etc ....and if I were not shooting a parallel comb gun ...it would make an even bigger difference.
One of the reason I like the Browning XS Skeet models ...with the adj combs...is they're parallel to the rib ...and a little adjustment seasonally ...can dial the gun in for me. Browning has more guns with parallel combs - than Beretta. The thicker grip area on the Browning Citoris, especially if they have a palm swell, fits my big paws better too. Berettas tend to be slimmer in the grip area...
If the Beretta fits you ....then in general, the Browning Citori's will not Fit you ...and vice versa...
